is alever 47 -having its outer end preferably telescoping asshown to adjustably vary the .length thereof, and terminatinglin a key 48.

The inner end of said lever is connected, by means of a link 49, with a pawl 50 pivoted at 51 to a bar 52 that is in turn pivoted on the shaft 34. Said bar 52 is provided on one side with a stop 53, and is formed with a downward extension 54 that normally contacts with the base 1. Fixed to the shaft 34 is a wheel 55 with which the pawl 50 is adapted to engage when lifted by lever 47, as more fully hereinafter described. The inner end of lever 47 is normally pressed downward by a coiled spring 56 and, if desired, the action of the latter may be supplemented by a leaf spring 57, as will be readily understood. Mounted in an extension 58 of bearing 46 is a stop screw 59, the same lying in the path of vertical movement of the inner end of lever 47 and thereby limiting its stroke, which may be varied by adjusting said screw vertically in extension 58.

From the above description the operation of my improved construction will be understood as follows: V17 ith the line guide arm 16 in the position shown in Fig. 3, the weight of the same and its carrier 15 is exerted on the cord 37 and through wheel 35 upon the shaft 34, but this tendency of the parts 15 and 16 to. drop to their lowermost position is resisted by the friction button 44 pressing against the side of wheel 36, the tension thereof being adjustably regulated by screw shaft 43. Now, when it is desired to feed the arm 16 downward the distance of a line of the copy supported on the plate 5, the key 48 of the lever 47 is depressed by the operator, which raises the inner end of said lever, and through link 49 initially tilts pawl 50 on bar 52, so that said pawl instantly engages the toothed wheel 55. The further movement of lever 47 lifts pawl 50 and bar 52 on the shaft 34 as a center, whereby toothed wheel 55 and shaft 34 are correspondingly rotated, and said rotation by unwinding cord 37 on wheel 35 permits a corresponding downward movement to carrier 15 and arm 16, which thus becomes a combined gravity and positive step by step feed that is checked by the spring-pressed button 44. To accommodate the step by step feed of arm 16 to different widths of lines on diiferent copy, I provide the set-screw 59, which by its adjustment will vary the stroke of lever 47. It will be observed that upon the release of key 48 and the return of lever 47 to its normal position, the extension 54 of bar 52 by contacting with base 1 will check the movement of said parts on the shaft 34 as a pivot, and pawl 50 will then rotate independently on its pivot 51 until it contacts with stop 53 on bar 52, which will bring said pawl just out of engagement with toothed wheel 55. When the arm 16 has reached its downward limit of movement, it may be instantly elevated to its uppermost position by pulling on chain 38, which by unwinding from wheel 36 will rotate shaft 34 to wind up cord 37 on wheel 35, and thereby elevate parts 15 and 16, it being observed that during this movement the pawl 50 is out of engagement with toothed Wheel 55, thereby offering no resistance to said movement.

By providing the elongated pivot pin 13 for the arm 16, the latter is freely movable bodily thereon towards and from the carrier 15, whereby it will adjust itself antomatieally to different thicknesses of copy held on the plate 5, and will not only lie flat against the surface of said copy, ven when the latter is quite bulky, but will also ride freely over projections in said copy caused by folds therein, as will be readily understood.

The normal operation of the copy retaining bars 21 and 27 will be readily understood, the bar 21 being retained against the eopY by the counter-weight 26, while the bar 27 a.

vided for by shifting cormtcr-weight 26 to its uppermost position, which will swing bar 21 on its pivots 23 to the position shown in dotted lines in Fig. 3, and by disengaging knife edge 30 from the upper series of teeth 31 on segment 32, and bringing it into engagement with the lower series of teeth thereon, which will swing bar 27 on its pivot s 29 to the position shown in dotted lines in Fig. 3, thereby materially shortening the dis tance between said bars 21 and 27. if desired, the counter-weight construction for bar 21 may be replaced by the knife edge and toothed segment construction of bar 27.

In Fig. 4 I have shown a slightly modified construction of support for the carrier and line guide arm, the rods 11 being replaced by a flat bar 60, and the carrier 15 by a carrier 61 shaped to embrace said bar, as shown, said carrier being provided with stops ()2 and 63 to limit the horizontal and vertical movements of the line guide arm. Again in Fig. 5 the carrier support 64 is still differently shaped, the carrier being in the shape of a sleeve 65. Furthermore, in this construction the line guide arm 66 is mounted to swing horizontally away from the plate 5, instead of vertically, as in the other figures, and to provide for its bodily movement toward and from the plate 5 I provide it with a double hinge 67, the operation of which will be obvious. In said construction I also provide upper and lower steps or guides 68 to maintain said arm in a hori- -zontal position.
